As you implied, she was rude regardless of the context (bdsm or vanilla) and asking her to leave was the proper thing to do.

The only alternative, one which I might have considered in today's era of cellphones, would have been a quick call to her dom. I've gotten one-off permission to punish in the past. One settled down realizing she was at risk. I received a sincere apology and much better behavior. The other... not so smart, though she certainly smarted in the long run.

I personally have a low tolerance for brats.
